TO ALL WHOM IT MAY CONCERN:

Bc it known that I, Tunononn It. COOK, of Saratoga Springs, Saratoga county, State of NewYork, have invented certain new and useful Improvements in the Construction of Barrclsliined with Sheet Metal; and I do hereby declare the following description and' accompanying drawings are sutlicient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvements without further invention or experiment.

The nature of my invention and improvements consists in rubbing down or burnishing out the sheet-metal lining against the inside of a wooden barrel, so as to make the sheet metal fit the wood closely on the inside, so that the wood will support the metal in` resisting the pressure on the inside of the barrel. In the accompanying drawings- Figure 1 is a barrel, with my improvements.-

Figure 2 is a vertical section, showing the interior.

In these drawings A A are the staves and B B the heads, both made of wood, in the usual form, or otherwise, and hooped by thchoops C C, making a strong barrel. To line the barrel with thin sheets of block tin, I take out both the heads B B and out the sheet metal into four pieces, widest in the middle, so as to itthe inside of' the barrel as near as I can, and put the sheets of metal into the staves and drive on the hoops,leaving out4 the heads, then fasten one corner at each end of the sheet to the staves by'clamping or otherwise. Then with a smooth hurnish'er of wood or metalI burnish down or rub the sheet metal out against the inside of the staves into all the hollows and sinuosities ofthe Woodas perfectly as it can readily be done. When one of the four sheets is rubbed down the edge fof the second one may be soldered to it and rubbed down in the same way, and the operation repeated forthe third and fourth sheets, when the edges of the first and fourth sheets may bc soldered together, completing the lining of the staves. Cut two pieces of the sheet metal of the proper size and form for each head, and laf)T them on the inside of the heads, and rub them down to any curves or cavities in the wood, and to the bevel of the edge; then mark the sheet metal to correspond with each head, and solderl them to each end of the lining of the staves on the outside, or one on the outside andthe other on the inside,

as may be preferred, and then put in the Wooden heads to "complete the barrel. But before soldering in bothheads a tube should be soldered to the lining for a bung, if a bung is required; also one or more tubes in the heads, as shown at I) E in the section, iig. 2, or as many tubes as are required should be'soldered to the sheetmetal lining. The barrel shown in the drawing is fitted to hold and transport the mineral 'water of Saratoga Springs, and is provided with a short tube, D, fitted to receive the screw-cap F, to close it. on the outside, which cap may be removed, and a cock or pipe screwed on in its place to draw the water from the barrel. This tube D has a ball-valve, G, in it to close it when there is pressure on the inside of the barrel. This ball-valve is prevented from getting too far from its seat by the bar H across the tube, and the cock or pipe applied tothe tubcfto drawthc water must have a projection on it of some kind to enter the tube and push the ball from its ,seat and hold it away to let the water runAby it in the tube, and run out of the barrel. The tube E is lsimilar to the tube D just described, and the tube D has a pipe, I, fastened t'o its inner end, which pipe extendsr down nearly to the bottom of the barrel, so that themineral water which runs through the pipe I to'll the barrel will run in quietly, and without splashing or agitation, that would tend to the liberation of any of the gases with which it is charged. And when it isdesrablc to ldraw water from the barrel it can be best done, and with the least loss of gases with which it is charged, by applying a pump to the tube E, and pumping air or gas into the barrel, and forcing the water up through the pipe I out of the tubes. Y

Having described my improvements in barrels lined with sheet metal- I claim rubbing out or burnishing down the metal lining-against the wood of the barrel to make the metal lining fit the inside of the barrel closely, substantially as described.

I claim as a new article of manufacture a wooden barrel, lined with sheet metal,- which is made to t the wood closely on the inside by being rubbed or burnished against it.

In testimony that the foregoing is a description of my improvements in barrels lined with 'sheet metal, I have hereunto signed my name in the presence of Witnesses.

THEODORE R. COOK.
